Formation of beta prime -SiAlON from a montmorillonite-polyacrylonitrile composite by carbothermal reduction: an NMR, TGA, XRD, and EM study

The products of carbothermal reduction in N sub 2 of a nanocomposite between dodecyl-ammonium-exchanged montmorillonite and polyacrylonitrile were studied. The only crystalline phase detected at 1000- 1300 degrees C was beta prime -SiAlON, having a much higher Si:Al ratio (7.05:1) than that of the p...

Zusammenfassung:The products of carbothermal reduction in N sub 2 of a nanocomposite between dodecyl-ammonium-exchanged montmorillonite and polyacrylonitrile were studied. The only crystalline phase detected at 1000- 1300 degrees C was beta prime -SiAlON, having a much higher Si:Al ratio (7.05:1) than that of the precursor clay (2.44:1). 53 refs.
